DUPLEX COUNTING MACHINE.

Application filed. February 24, 1923. Serial No. 620,878.

T0 (/71 'WIIOHL it may concern:

Be it known that. I, CUn'ris HUssnY Vniinnn. a citizen of the United States. residing in Hartford, in the State of Connecticut, have invented certain new and use ful Improvements in Duplex Counting Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

In the applica'ion of counting machines to other machines for the purpose of reg istering the number'of operations of the main machine, such as a loom, for example, it is sometimes desirable to provide two counting mechanisms either one of which can be put into operative relation with the moving part of the main machine so that the number of operations during a given period of time, can be registered independently of the number of operations during another given period of time, as, for example, the number of operations or picks of a loom during the day shift and the number of picks of the same loom during the night shift. The object of this invention is to providea duplex counting machine of the general class referred to, with improved devices whereby either counting mechanism at will can be connected operae tively with the moving part of the main machine. Incidentally provision is made for maintaining in proper working condition the working parts of a numbering ma chine which, as in the particular use suggested, is subjected. to constant vibration and wear. The invention will be more fully explained hereinafter with reference to the accompanying drawings in which it is illustrated and in which I Figure 1 is. a view in elevation of the improved duplex numbering machine.

Figure 2 is a VleW of the same in section on the plane indicated by the broken line 2-2 of Figure 1.

Figure 3 is a view of the same in elevation as seen from the right hand in Figure 1.

Figure 4 is a view in section indicated by the broken line ure 1.

on the plane 44 of Fig- T he working parts of the improved dulost motion relation with one gear sight openings (1 through which the two sets of number wheels may be read. wo numbering machines may be constructed and arranged to operate in any usual or suitable manner, except for the provision of the separating plates 0. In the operation of looms the loom counters are often subjected to very severe vibration which has been found to occasion side wear of the number wheels to such an extent that. sometimes becomes excessive and the transmitting gears and pinions cease to function properly and become tied up. For the purpose. of overcoming this difficulty the separating plates 0. shown in Figure 2 are placed between the several number wheels I) and the corresponding transmitting pinions I). They are fitted into the notched edges of the frame work which supports the number wheels and the transmitting devices, at both the to and the bottom, and are therefore placed accurately and held securely.

Each of the counting machines is pro vided as usual with a gear d by which the machine is driven and in the improved machine the two gears d are adapted to be engaged, the one or the other, by a common driving pinion e, which is shiftable into engagement with one or the other of the gears d as may be required. As shown, the com mon driving pinion e is mounted on a spindle e which is supported in a swinging yoke f carried by a'spindle f. A locking yoke g, pivoted at g co-operates with the spindle e to hold the pinion e in working d or the other. The pinion e is in constant engagement with a driving worm h on a shaft h which carries a worm if, in engagement with a worm h on a shaft h, the latter being coupled, as at k to the moving part of the loom or main machine the operations of which are to be registered 011 the counting machines. "lhe spindle f, which carries the yoke f, has secured thereto, outside of the casing a, an arm f which may be provided with a locking detent f for co-operation with a locking plate f. A spring detent co-operates with the driving gear at to lock the train of number wheels a ainst movement by vibrations. The spin le f is at right angles to the worm h and in close proximity thereto at one side, while the pinion is at the other side of the Worm so that it is oscillated through the small are necessary to effect engagement with one or the other of the two gears d Without disengagement from the worm.

In the operation of the improved duplex counter it will be understood that the shaft h is driven continuously from the moving part of the 1nachine,cthe operations of which are to be registered on the counting machine and that the driving pinion e is therefore driven continuously from the worm k. If the pinion e is in engagement with one of the wheels d. as the upper, as shown in Figure 4, and it should be desired, as at the end of the day shift, to change the operating connection to the other or upper counting machine. the lever f is manipu lated and the driving pinion e is shifted .therehy from engagement with the upper driving gear 03 to the lower driving gear kl. The pinion will be held in operative engagement with one gear or the other by the locking member g.

I claim as my invention:

1. A duplex counter comprising two counting machines mounted on parallel axes, each having a driving gear, a common shiftable driving pinion for engagement with one gear or the other, a driving worm, a swinging yoke mounted at one side of the WOIlIl and supporting the pinion at the other side of the worm in constant engagement therewith. and means to operate the yoke to shift the driving pinion into engagement with one gear or the other.

2. In a counting machine, the combina tion of a series of number wheels, a series of transmission mechanisms including each a transmitting pinion external to the number wheels, and a series of separating plates co-operating with the number wheels and the transmitting pinions to prevent relative lateral movement thereof.
